Re:Throughput computing. NOT! (Score 1)

For Java, individual JVMs have been seen to run happily with good scaling at 16 CPUs now, and maybe more. For database applications like Oracle and DB2 there have been reports of linear scale at 72 CPUs. So, Amdahl's law (and I met him - he's a great man hardly given the credit due him!) really applies to a particular application or algorithm with both serial and parallel components. As the number of CPUs rises, the serial portion tends to dominate - but that's not relevant for *separate* applications!
